ABSTRACT:
This power plant utilizes a multi-cylinder hydraulic engine that has a plurality of pistons and cylinders arranged for reciprocal movement. Each piston is powered by a hydraulic fluid or air pressure. The fluid exhausted from one cylinder is sent to another cylinder to act as the inlet fluid to move that cylinder. The engine requires piston and cylinder arrangements in sets or multiples of four (such as 4, 8, 12, 16 and so forth) to provide a balanced system. The engine can be designed in many different arrangements such as four cylinder in line, four cylinder radial, eight cylinder radial, eight cylinder V-shaped, eight cylinder opposed and so forth. These cylinder arrangements can be linked together if desired to provide multiple engine power plants. The piston used in the present invention is a spool-type piston having distinct sections which create distinct upper and lower fluid areas in the cylinder. The hydraulic engine can be coupled in a power plant arrangement with a source of fluid pressure such as a pump arrangement located on pontoons on a body of water subject to tidal or wave movements.
